We're one step closer to having a complete list of season finale dates for all of our favorite network TV shows now that NBC has made it official. There's a wide range, starting at the end of March with Whitney and going all the way until the latter half of June with The Voice and Hannibal.

Whitney, The New Normal and The Office all have one-hour finales (the first two of these shows are back-to-back episodes). Besides All-Star Celebrity Apprentice and The Voice, Law & Order: SVU will wrap up with a two-hour episode as well.

And a finale date was also announced for Hannibal, a new drama that doesn't debut until April 4.

We also found out today that America's Got Talent season 8 will premiere on Tuesday, June 4 from 9-11pm (and continuing the next night with an hour-long episode at 8pm), with new judges Mel B and Heidi Klum joining returning favorites Howard Stern and Howie Mandel. (This marks a change from last year when NBC premiered the show during May sweeps.) The live shows begin on Tuesday, July 23 (9-11pm) and Wednesday, July 24 (8-9pm).

You might notice that Smash isn't included in the above lineup. I guess NBC figures they don't need to announce an end-date since they're unofficially cancelling it by burning off the remaining episodes on Saturdays beginning April 6. But if they stick to the schedule they're currently on, the season 2 (and most likely series) finale should air on May 25.
